3.1. Modeling on the relationship between the responsible actors
and traceability system
In order to set up an efficient vegetable traceability system, the
first step is to define the user requirements for the vegetables
supply chain (Dannson et al., 2004). A system-level approach is
used to develop models for implementing the traceability system.
The user requirements of the traceability system are defined by the
UML Use Case Diagram Technique (Eriksson & Penker, 2000, pp.
17e57). The Use Case Diagrams are closely connected to scenarios.
A scenario is an example of what happens when someone interacts
with the system (Bechini et al., 2008). One of the most important
goals of defining the system requirements is to have synchronization
among the requirements of all the actors involved.
Use Case Diagrams demonstrate the relationship between the
responsible actors and traceability system. The observation of the
system by use case can help to understanding the most important
part of the system and meet users’ requirements and expectations
(Zhang, Feng, Xu, & Hu, 2011). By means of use cases, the function of
the system modules becomes clearer. Fig. 3 shows the consumer as
playing the key role in the Use Case Diagram:
Baseline information: The farmer will record in the system the
farming practices used for each specific vegetable. There will also
be recorded data such as the seed variety used, planting date,
chemical application, harvesting etc. For specialty crops will also be
needed the recording of organic practices information. The transporter
should be able to enter the transporting details used in the system. Depending on the transporting process, these may include
temperature, transporting time, distance, etc. The vendor should
enter the sales information, including weight, batch, variety, etc.
The inspectors should be able to provide data showing whether the
production complies with the food safety regulations or not,
including information on pesticide residues, heavy metal content,
moisture content, etc.
Processed information: All data will be uploaded into the system
and the demands received for them will be authenticated based on
the data stored in the system. For example, upon request, the
system should be able to provide data for supporting the organic
farming or processing practices. The system users (consumers)
should be able to find the information based on the data stored in
the system.

5. Conclusions and discussions
The implementation of a traceability system in the vegetable
supply chain is a complex task. The foundation for any possible
discussion about the development of this sort of systems is represented
by the taking-up of a generic data model for traceability.
Such a model has been suggested and expressed using UML,
describing its basic classes and the patterns used to represent the
lot behavior throughout the vegetable supply chain.
1) A series of UML diagrams were developed so as to represent
a method for modeling the product, process, and quality as well
as the transformation information by any link in the value
chain. All the traceability data captured must be linked to
a uniquely identified TU (Traceability Unit).
2) The system performs a real-time tracking of the process control
functions by using the UML modeling based on the accomplishment
of the vegetable processing information management
functions, thus making easier the quality improvement of
the processed products and reducing the product recall costs;
furthermore, the system successfully handles the whole
process of vegetable quality tracking and tracing and provides
rather detailed traceability records to consumers.
3) The system uses a powerful ASP.NET, ADO.NET technology with
theWindows2003 þ .NET Framework þ SQL Server 2005 service
platform. As a development tool, Visual Studio applies to developing
the B/S mode Web-based for processing the vegetables
quality and safety traceability system; the Web-mode system is
used to achieve a complete separation of codes and pages, thus
being improved the system development and maintenance
efficiency.
Compared with the traditional system, it achieves a crosscommunication
information flow between manager, worker and
consumer. The system testing and experiment evaluation proved to
be some effective vegetable quality management tools that lead to
maximization of the vegetable workflow monitoring and recording.
It effectively improves the probability of high quality and safety
during the production process through enabling constant monitoring
of the critical parameters in this process.
In order to achieve the traceability goals along the vegetable
supply chain, the businesses should focus both on internal and
chain traceability.
